I tried on a pair of Lacrosse 4x Alpha's. They are a hybrid rubber/snakeboot. They were fairly comfortable for the 150.00 price tag.
I would love to own a pair of Chippewa's, but I just can't justify 300.00 on a pair of boots. I tried on one of the moccasin toe Chippewa's on at Mark's in birmingham, they are an 18" boot, I'm 5'10" and they were all the way up to the back of my knee, so much so it was a little uncomfortable. Having owned many pairs of good leather boots beforehand, I bet they are pretty comfortable once they are good and broke in.
